To make a long story short, I switched ISP's. I've been using Thunderbird for e-mail, but couldn't get it to work with WOW. I'm now using Windows Live Mail. When I tried to open a .pps (PowerPoint) file from an e-mail, I got an error message saying I needed to associate the file type with a program. I've got Microsoft Office PowerPoint Viewer installed and it shows in the start menu but not in the list of programs when I click on "set your default programs". When I click on "Associate a file type with a program" and scroll down to .pps, it has PowerPoint Viewer listed next to it. I'm stumped. Any help would be appreciated.
